check relays on working circuit(do voltage drop test) could be a weak relay which checks out ok wheck tested cold but heat affects resistace so best to test it in operation or just change it.

I know you said you checked all the relays, but it sounds like the AutoShutDown relay.

Kevin, You'd better listen to Woodrow and Joe, this is a common problem on your Dak. This has been identified before on this forum. Do a search!
